A Hairy Dilemma

About every six months I get bored with my hair, which has led me to just randomly go to a hairdresser and tell them to take drastic measures and cut off all my hair. Last winter, I had this little gem of a hairstyle:

And then around this time last year, I cut my hair into this trendy bob (thanks for the inspiration Posh & Katie).

Now my hair is growing out and I'm starting to get lazy. I have no more bangs to speak of, lots of split ends, and most days I put my hair in a bun at the nape of my neck and twist my somewhat existent bangs into this curly q on the side of my head (and sometimes a Lauren Conrad braid works). 

But I'm getting bored again people. And I need some ideas.

I want something obviously that screams "I am a working professional" but can also be hot for the weekend. I also have to mention that I'm trying to grow my hair out to do Locks of Love. 

I have narrowed my options down to the following and I need your help in determing which hairstyle will get to grace my head for the next few months. And is obviously OK'ed for work situations. 

Option 1: Not overdone bangs, subtle layers. 

Option 2: back to a more blunt fringe with no layers

Option 3: something simpler, no bangs, just great long layers

So you tell me Working Girls - which is the best option?
